Cormorants are one of famous fish-eating birds, there are different types and shapes due to different distribution areas, but they are all medium-to-large birds that feed on fish. Because of their shape advantages, they can quickly skim the water surface or Dive into the water to catch delicious fish. According to research, each adult cormorants needs to eat about 500g of fish per day, and at the same time, the fish it hurts during predation will also die due to wounds. In Europe, North America and other regions, the number of cormorants in the same habitat is relatively large, so the bird predation brought by cormorants will bring great losses and negative impacts on commercial fishery.

In many places, killing cormorants has been allowed by law, although some countries still list them as protected animals. There are many methods of cormorant control, such as net netting, habitat modification, pyrotechnics, spotlights, egg oiling, etc., but most of the methods are based on the premise of harming the cormorant, and they need to be improved in terms of sustainability. So people have been looking forward to the emergence of a cormorant scarer that can take into account the interests of both humans and Cormorants.

In recent years, laser bird deterrent has become more and more popular. Many fishery managers have also proposed to use lasers to protect fish ponds from cormorant predation. Is it effective? Some authoritative websites gave the answer:

“Hand-held lasers have been used successfully to disperse roosting cormorants and are most effective in low light conditions, such as at night roosts. In addition, lasers are silent and can be used to move cormorants without disturbing other non-target species.”

As a silent way of repelling birds, laser bird scarer greatly reduces the impact on fish, and is not affected by the pattern and size of aquaculture facilities. And you can choose automatic or hand-held laser bird repellent according to the area of the fish pond, which will be an effective tool for daily management.
